ICE-FORMING AND PRESERVING ROOM.

SPECIFICATION forming part of Letters Patent No. 485,805, dated November 8, 1892.

Application filed October 13, 1891. Serial No. 408.570. (No model To all whom it may concern,.-

Be it known that I, JAMES MONROE Rosen, of Nyack, county of Rockland, and State of New York, have invented a certain new and useful Improvement in Ice-Forming and Preserving Rooms, of which the following is a specification.

This invention relates to rooms or receptacles for cold-storage of fruits, vegetables, zc., and within which ice is formed for such refrigeration; and the invention consists in the construction and novel arrangement of parts, as hereinafter set forth.

In the accompanying drawings, Figure lis a transverse vertical section of a device embodying my invention. Fig. 2 is a horizontal section on the line o; fr of Fig. l. Fig. 3 is an enlarged sectional detail. Fig. 4 is an enlarged View showing the fines extending longitudinally at the roof-ridge.

Referring by letter to the drawings, A des ignates the outer vertical walls of a room, and A shows the inner vertical walls of the room. These walls A A form a double wall at all the vertical sides of the room and they may be constructed of any suitable material-such, for instance, as sheathing-boards nailed to studs for the outer wall and any suitable boards nailed to studs for the inner walls. There is a space formed between the outer and inner walls, which is closely packed with insulating material a', such as sawdust. The roof preferably has a pitch from its center to opposite side walls, and the roof, like the side walls, is made double-that is, it consists of the inner portion A2, supported on rafters, and the outer portion A2, also supported on rafters. The space between the portions A2 A3 of the roof is closely packedwvith insulating material a. Preferably a layer of tarred or similar paper a2 is placed between the material a and the boards of the inner-roof portion A2 and a similar paper a2 may be laid on the sheathing-boards of the roof portion A3. Above the portion A3 of the roof I desire to have a free circulation of air. I therefore provide iiues ct, which are formed by securing any desired number of strips a5 to the upper surface of the roof portion A3, and placing a shingle or similar roofing A4 on the strips. These ducts a4 are open at the bottom or at the eaves of the structure and at the upper end are open to the atmosphere. Preferably the upper ends of the ducts will open into a hooded duct A5, extending longitudinally at the roof-ridge and having suitable openings in its sides.

A flooring or partition B divides the structure into an upper chamber B' and a lower chamber B2. The Iiooring B is supported on beams b, which rest upon or are framed into standards b. The chamber B2 has a flooring B3, which is preferably covered with concrete or similar non-conducting material h2. rThe flooring B is preferably double and has its space closely packed with insulating material b3, such as sawdust. At opposite sides the floor B is provided with a series of openings B4, which provide air communication between the chambers B' B2, so that a circulation of cold dry air may be maintained through the chamber B2, within which material to be preserved is placed, as will more `fully appear hereinafter. For the purpose of alfordng light the walls of the chamber B may be provided with windows, as shown.

C designates an ice-making tank located in the upper chamber B', and in Fig. l C represents a solid body of ice formed therein. The tank C has a less surface area than the fioor B and is located between the opposite openings B4 for a purpose hereinafter specitied. The tank C consists of a platform c, resting on strips c', which raise the platform slightly above the surface of the floor B, so that there is a space for the free circulation of air beneath the tank, and side walls c2, which extend upward from the platform c. The tank is open at the t-op and one of the sides is made in sections and removable, so that after a body of ice shall have been formed the said side may be moved to allow the passage of air over the exposed surfaces of the ice in its transit to the lower or preserving chamber. The inner surfaces of the tank are suitably lined with metal or other waterproof material and its joints are rendered water-tight byany suitable means. The

side walls of the tank preferably nare outward toward the top, so that the expansion of the water While freezing will be directed upward and not laterally.

D designates conducting tubes or funnels for conducting the air from the outer side of IOO the structure to the tank C for the purpose of freezing the water contained therein. There maybe any desired number of these conducting-tubes and they may be of any desired form. I have, however, shown but three conductors, formed in the shape ot' hoods, communicating with the outer air through 'apertures in one of the end Walls of the structure and extending a short distance over the tank. It is to be understood that the ice is formed only during a time when the temperature is sufficiently low, or during the winter months, and thata sufticient quantity of mass is formed to last through the warmer weather for preserving fruits, dac., in the chamber B2. Of course during the process of forming ice the openings B4 are tightly sealed by hatches or bags of sawdust, as shown in Figs. l and 2, and duringwarm Weather thepassages through the Wall communicating with the conductingtubes D are to be tightly sealed, and I find that bags of sawdust d serve the purpose of sealing, and blinds or shutters d may also be closed against the A Having described the mechanical construction of my invention, I will now describe the process of formingice therein and ot' utilizing the icev for preserving.

Water is placed in the tank to a depth of about three inch es and this is allowed to freeze by admitting cold outside air through the conducting-tubes D. When this first layer of Wateris frozen sufticiently hard, more Water is poured upon it and allowed to freeze, and this process is carried on until the tank is lilled, 0r nearly so, with a solid mass of ice. Vhen it is desired to utilize the ice for preserving material in the lower chamber, any desired number of the hatches are removed from the openings B4 and one ot the tank-walls removed. The air in passing over the ice will be thoroughly cooled and dried, and it Will circulate, as indicated by the arrows, through the openings B4 at one side of the-ice into the lower chamber and back again through the openings B4 at the opposite side of the ice. It

is obvious that the iioW of air to and from the lower chamber may be regulated by closing more or less of the openings B4.

I have described and shown my ice-chamber and preserving-chamber as arranged one above the other; but I do not Wish to be confined to this construction, as it is obvious that the .chambers may be placed side by -side With the air-circulating apertures or openings B4 in the top and bottom of the dividing partition. Neither do I Wish to be confined to the described construction ot` my ice-tank, as its walls may be made without any incline with good results.

.Having described n1yinvention,what Iclaim, and desire to secure by Letters Patent, in an ice-forming chamber and preserving-room, 1s-

l. A refrigerating and preserving building comprising double side walls A A', packed with insulating material, a roof having the inner portion A2 and outer portion A3, each supported on an independent series of rafters, insulating material d between said outer and inner portions, a layer a2 of tarred Inaterial between the material d and the inner roof portion, a similar-layer a3 above the outer roof portion, a series of parallel contiguous air-ducts above the outer roof portion A2 and covered by the rooting proper, said ducts running froni each eave to the ridge and communicating with the atmosphere at both ends, a iiooring B3, havinga non-conducting surface, and an intermediate horizontal transverse partition B, dividing the interior into an upper and a lower compartment, substantially as specified.

2. In an ice-forming and preserving building, the combination, With the upper chamber B', surrounded on all sides by double packed Walls and rooting, said rooting having aseries of air-ducts therein, of an ice-forming tank located in said chamber and havingaless surface area than said chamber, the Walls of said tank being flaring and one removable, a series of ducts or hoods D,communicating with the outer air through a wall of the building and extending over said tank, and an adjacent preserving-chamber having openings com-v municating with the chamber B and means for sealing said openings and the hoods or ducts D when desired, substantially as specitied.
